Bitcoin experienced significant volatility, fluctuating between $86,000 and $90,000 in the past 24 hours. This comes as traders anticipate the U.S. November inflation report, which is expected to reveal a 3.1% annual rise in the Consumer Price Index (CPI). The data could influence expectations regarding Federal Reserve rate cuts and impact Bitcoin's price trajectory. Additionally, the potential exclusion of digital-asset firms from MSCI indices may also affect market sentiment.
